Garrison Keillor No Lifelong Lutheran?

There are things I've taken for granted: the sun will rise in the morning, the Red Sox will choke at a critical time at the end of the season, and Garrison Keillor is a lifelong Lutheran. But apparently the last is not correct. Someone highly placed in a Lutheran organization - I kid you not - mentioned this today in an interview on a totally unrelated subject. That is, unrelated to Keillor, not to the religion. When I searched on the web, this interview at ChristianityToday.com confirmed it. (Ironically the piece was posted on June 6, 2006 - I'll leave the numerical representation to the devout and superstitious.) That's one out of three down. Wait ... the Sox did win the Series a few years ago. I'm hoping that the overturning of my life's assumptions doesn't continue.
